A seat base having protruding members fixed to the underside thereof that are positioned within mating recesses formed in the fenderdeck of a vehicle. The base is clamped to the fenderdeck by a pair of screws. The screws and mating features defined between the seat base and fenderdeck secure the base to the vehicle to prevent shifting of the seat during operation. If the screws become loosened during operation, the protruding members will engage side walls of the recesses to prevent the base from shifting fore and aft suddenly and unexpectedly, and to alert the operator that the screws have become loosened.
